On September 4th, most areas of northern Xinjiang ushered in an autumn rain, and the temperature The temperature has dropped to around 11-23°C. In a cotton field located in Bole City, Xinjiang, cotton bolls at the bottom have been seen spewing out fluff, and the epidermal layer of some autumn top peaches has also shown signs of imminent cracking. Judging from the peach-bearing situation, the yield per unit area is expected to be little changed compared with previous years.
According to experienced planting experts, this time last year, there were already It is time to start spraying defoliants, which is generally later this year. The timing of spraying defoliants must be grasped. Different cotton fields must determine the spraying time according to the actual situation. If the top peaches are not fully mature, spraying too early will cause Premature senescence of cotton plants not only affects the weight of single bolls, but also affects the cotton quality indicators. If it is too late, the cotton plants will become green and mature late, and the poor defoliation effect will also cause The impurity content of seed cotton is too high.
